You don't the carbon fiber strut brace think it makes a difference? We're talking Mizuno here, dude!
It does, and I have one, but that one is woven special with a resin, and is subject to very little motion. In the DBA, it is also screwed down every foot or so.
Icarus raises a good point though. And, I know I just "know" that CF wouldn't support the loading on that kind of gusseting. That part will not only see pull, but also push, and twist. Just my experience that CF cannot do all of that.
I remember when one of the F1 cars suspension arms just exploded into dust, and I saw the film. I remember thinking "what made you think they would hold up to that?", but at least it was an unusual occurrence.
